Three different approaches of freezing rabbit tibia bones are demonstrated. Intramedullary freezing seems to be the safest method to avoid soft tissue necrosis. Bone specimens removed immediately after the freezing-thawing process showed electron optically evidence of irreversible damage of bone cells in all cases.

[Long-term observation of osteochondrosis dissecans of the hip (author's transl)].

The article presents treatment results in a group of 21 patients (22 joints) suffering from osteochondrosis dissecans of the hip, the minimum observation period being 10 years (average 14 years). By means of surgical treatment, it was possible to achieve healing of the osteochondral fragments in nine out of 16 cases. Such healing was not achieved without surgical treatment; in two-thirds of these cases, an increasing osteoarthrosis of the hip was observed. Among the surgical measures, a combination of adduction osteotomy together with forage, yielded the best success quota (5 healings as a result of 5 operations), whereas adduction osteotomy without forage resulted in healing in 2 cases only out of a total of 16 operated patients.

Effects and side effects of radiosynovectomy with Yttrium 90 on rheumatic joint cartilage.

8 and 12 weeks after Synovectomy with Yttrium 90, cartilage specimens from the femoral condyle of 8 patients with R.A. were examined. Cellular and matrix damage could be detected. Intracellular particles containing Circonium, an Yttrium decay-product could be found using microprobe X-ray analysis. This was verified in experimentally induced arthritis in the rat.

The transgluteal approach to the hip joint.

A modified transgluteal approach to the hip joint without osteotomy of the trochanter is described. The advantage of this approach is a better view of the acetabular rim, prevention of gluteal muscle damage and protection of the superior gluteal nerve.

The Chiari pelvic osteotomy--indications and results.

Chiaris pelvic osteotomy with or without intertrochanteric osteotomy was performed in more than 100 cases during the past ten years. An evaluation of 97 operations showed good results in younger patients (age groups from 5-17 years). In adults with evident signs of arthrosis a higher rate of failures was obvious and therefore the indication for the pelvic osteotomy in this group of patients should be restricted.

[Critical findings of captitate osteotomy in the treatment of lunatomalacia].

Five patients with Kienböck's disease had been treated by an osteotomy of the capitate (GRANER) with three poor results. In two cases necrosis of the capitate bone and resorption of the cancellous bone graft were obvious, perhaps due to damage of important vascular structures. Anatomical studies which have been carried out, showed that the main vessel of the capitate arises from the deep palmar arch and joints the bone on its ulnar-palmar and distal aspect. In order to achieve more satisfactory results with this operative procedure, the authors feel that it is important to protect the above mentioned vessel and indicate a more proximal osteotomy-site of the capitate bone.

[Innominate osteotomy (Chiari) for the treatment of coxa magna--preliminary results of 17 patients (author's transl)].

This is a report on the validity of treatment of coxa magna hips resulting from Legg-Calvé-Perthes-disease or hip dislocation by Chiari's pelvic osteotomy. Only severely deformed, incongruous and subluxated hips were treated by this operation. The aim of treatment is the development of congruency with a well covered femoral head to prevent an early occurence of osteoarthritis of the hip joint. Our results were compared with the results of nonoperative treatment of comparable patient groups.

[Problems and results of Arthroplasty of the Knee Joint].

Since 1970 43 total knee arthroplasties were performed and the results of 34 operations reviewed. The average follow-up period was 2.4 years with a minimum of 6 months. We used 2 McIntosh, 8 Sledge, 9 Shiers, 8 Guepar, 3 Geomedic, 4 GSB prosthesis. The clinical results were very good in 56.2%. The failure and the high rate of loosening of the Shiers-Joint are stressed.

The treatment of chronic knee joint synovitis with radioactive isotops (author's transl).

On the basis of 77 cases report is given on the treatment of chronic synovitis of the knee in rheumatoid arthritis with radioactive isotopes. Gold 198 and Yttrium90 have been applicated. During an observation period up to 6 years a follow-up on 46 knee joints has been carried out. Very good and good results could be achieved in 50% of these cases.

[The results of Chiari's medial displacement osteotomy].

Results of follow-up investigations on 45 patients with hip operated between 1968 and 1973 after the method of Chiari are reported by the authors. The post-operative development of the C.E. angle (Wiberg) and of the acetabular inclination angle (v. Lanz) are discussed. Attention is drawn to the necessity of X-ray films taken in a second projection (Fauxprofil view). With the aid of arthrography of the hip joint it is demonstrated that the most important demands of acetabulum formation surgery, namely the antomical congruence of the joint components, can be achieved by means of pelvic osteotomy after the method of Chiari.
